SAVE HUNDREDS WITH EARLY BIRD PRICING Session I: Improving Operations Optimizing Slope Angles with Controlled Blasting, Slope Monitoring, and Good Communication Keith Taylor, Sr. Geotechnical Engineer, Freeport-McMoRan Is Bigger Still Better? Considerations for increasing size of haulage equipment By M. Dotto, T.G. Joseph, M. Curley Equipment selection is one of the most important decisions made in mine planning. This study analyzes hauler scale impacts on aspects not currently incorporated into conventional mine planning, including expan- sion of roads to accommodate larger equipment, road layer thickness variation depending on hauler size, and fuel consumption and emissions. The Critical Link Between Loader Productivity, Operator Performance and Mining Costs By Andrew Jessett, CEO, MineWare This presentation explores the critical link between loader productivity, operator performance and the overall cost of mining as far as: • Performance of material loading assets heavily infl uence the success of the downstream mining processes; • Why ineffi ciencies on the front end have dramatic repercussions to the overall value stream; and • Why the variation in performance between operators on loading equipment will continue to signifi cantly affect the success factor for the whole load-and-haul process. Improving Ingress/Egress Systems on Mobile Equipment By William L Porter & Jonisha P Pollard; National Institute for Occupational Safety and Health (NIOSH), Pittsburgh Mining Research Division Slips and falls from heavy mobile equipment commonly occuring during the ingress/egress process with root causes being largely unknown. The NIOSH Mining program conducted research to determine injury mech- anism and equipment characteristics associated with front end loader ingress/egress injuries. This work included reviewing injuries reported to MSHA and identifying the elements of the system that equipment operators feel create diffi culty while getting on or off of their equipment. Use of Lighting Technology on Mobile Equipment By Yazi Fletcher, Chief Technical Offi cer, Phoenix Lighting In an industry that continues to stress the importance of effi ciency, LED lighting is opening up a whole new world of options. Companies are able to utilize their resources like never before while gaining productivity and cost benefi ts from technology. LEDs offer numerous benefi ts to the operation needs of the surface mining industry. They are more durable than traditional lighting, dramatically decrease energy expenses, and virtually eliminate maintenance. Session II: Haulage Strategies Bringing New Life to DC Haul Trucks with an AC Retrofi t Package By Ben Balbech, Heavy Industry and Power Systems Manager, Flanders With custom designed AC wheel motors built into the DC motor frames and a high performance liquid cooled IGBT drive package that drops into the existing DC drive footprint, old DC haul trucks can now meet or exceed the capability of modern AC haul trucks. An all new, open, fl exible, industry-standard control package makes troubleshooting and diagnostic simple. Advanced traction control with a virtual limited slip rear differential greatly improves truck tracking in slippery conditions. Mine Haulage Simulation: A Tool Towards Managing Uncertainty By Hooman Askari-Nasab, Mohammad Tabesh, and Shiv Upadhyay A mine and extraction simulation operational planning tool with Excel input/output interface and automated reporting has been developed, vali- dated and used as part of the short-range planning of a large-scale oil sands open pit operation in Canada. The simulation tool takes the production schedule as an input and imitates the truck-shovel haulage-systems and its interaction with the extraction plant including crushers and downstream assets. The simulation tool accurately reported the major system's KPIs at 95% level of statistical confi dence within 3% accuracy of the historical dispatch data for the project. This tool gives the planner capability to assess the impact of changing operational scenarios such as stockpiling, different sizes of mixed-fl eet trucks, and introduction of new haul-roads into to the mine plan. Normalized results of the project will be presented. Can 'Big Data' Answer the Big Question: How Do My Haul Roads Perform? By Roger Thompson, Professor of Mining Engineering, Curtin University, Western Australia School of Mines Much has been made about the potential of big data to transform mining and how to capture, evaluate and share this information with those deci- sion makers that value the data. While the amount of data available from operations and equipment is increasing, only a fraction of its full value is currently being extracted. Coordinated Operator Training By Graham Upton, Director of Business Development, Doron Precision Systems Simulator training reduces accidents and provides effi ciency for mine operations. Typically, simulators train one operator at a time for par- ticular operations, whether it be haul truck, shovel operator, or other equipment operator training. A new approach allows operators of two or more vehicles to be fully integrated, immersed, and coordinated within a training scenario. Using multiple simulators, one instructor can train several operators at a time. 2017 May 7-10, 2017 Wigwam Resort Phoenix, AZ USA HAULAGE & LOADING EXHIBITION AND CONFERENCE
